What with her being as receptive (pardon the pun!) to sexual pleasure as she was, I didn't see any reason not to make my own approaching climax better, too — and started thrusting into her with longer, slower strokes to increase the pressure I could feel building inside me. Karen let me know that she thought that was just dandy with an increase in the moans and verbal encouragement she was giving voice to.
When my cock signalled that it was going to happen now, rather than slam myself into her the way I wanted to, I held her by the hips and tried to press myself as far into her as I could — even as I felt her clamp down on me with the beginning of her third orgasm since I'd gotten behind her.
The tightening of her vagina was in almost perfect counterpoint to the pulses of cum that erupted from the end of my cock — she would clench around me and intensify my pleasure, then relax enough to let me try to coat her tonsils with my jism before she tightened around me again.
By the time it was over, both of us were panting; I got an idea of how intense it had been for Karen when I felt her begin to wobble slightly in front of me. Wanting to enjoy the warm confines of her for a little longer, I carefully guided her forward so that she could lay down on the bed while I stayed right behind her. Supporting my weight on my elbows, I was able to cover her body with mine while keeping my slowly-deflating cock inside her.
I'd gotten my breath back, and had applied a number of soft kisses to her shoulder and ear and cheek when I heard her quietly ask "Is it always going to feel that good when I have sex? Or were you doing something special to make it better for me?"
I kissed her shoulder again before answering "I wasn't doing anything 'special' for you, sweetheart, except trying to make you feel good and happy, too. If you're with a guy that cares for you, then I don't see any reason why it shouldn't feel that good for you every time."
She considered that for a few moments, then told me "And I guess if he doesn't care if he makes me happy or not, there really isn't any reason to do it, is there?"
" I don't think so, but that's something you have to decide for yourself."
Another couple of seconds went by before she told me "I think I'd rather feel this good a few times, instead of doing it more often, but not liking it as much. What do you call it? Quality versus quantity?"
I kissed her cheek, then answered "Yeah, that's what I call it."
After that, the two of us just lay there for a while longer; our companionable silence was interrupted only when she told me "I can feel you're almost ready to pull loose of me. I'd like to stay here, 'cause it's so nice being with you like this, but I don't want to make a mess on your bed, either. So if you'll get off of me when it happens, I can hold your stuff inside long enough to get into the bathroom. Then we can take a shower, if you want."
I nibbled on her earlobe with my lips, causing her to scrunch her shoulder, before I answered
"Yeah, I can do that. You want some time in the bathroom alone, then?"
"Yeah, a couple minutes, if it's okay."
"Of course it is, honey.", I answered, before kissing her shoulder again.
A minute later, I felt myself uncork from her, and quickly moved off of her. She raised her hips enough to press her hand over the entrance to her vagina before getting out of bed and unabashedly heading for the bathroom. I gave her well past her requested couple of minutes before getting up and going in to join her. Our shower wasn't quite as playful as it had been the night before, but was easily more loving and affectionate. She dried me off, then I sat on the commode to make it a little easier as I did the same for her. When I was done, I put my hands on her hips and gently guided her to face me so I could tell her "Karen, honey, I really liked the things we did together last night, and again this morning. But I want to make sure you know that I love you for who you are in your heart, and what's in your mind, not because of the things we do with each other. If you want us to keep making love like that, that's fine with me — just like it's fine if you want us to stop, too. No matter what happens between us, I still love you, and I always will. Okay?"
The smile she gave me went straight to my heart before she answered "I know you love me, Uncle Ted, and you'd still love me if I didn't want us to do stuff together. I'd still love you just as much if you told me that you didn't think we should be like this together. But if we can make each other feel good like we did last night and this morning, I'd like that — it's a way we can show how much we love each other. Let's just enjoy what we have, and not worry about it, all right?"
"Okay, sweetheart." I answered, smiling back at her. She leaned forward to give me a tender kiss on the lips before standing up again and saying "Now, I think it's time we got dressed and went upstairs — we're already late for breakfast!"
I stood up, and Karen took my hand and led the way to where we'd left our clothes. Once both of us were dressed, she held hands with me again as we made our way upstairs. There, we found that we'd almost missed breakfast completely, and making me think that we'd have to take care of fixing our own. Except that after Teresa glanced at Karen, then looked at her again more closely, she asked the youngster "Are you okay, honey?"
I could see a certain serenity on Karen's face as she answered "I'm fine, Mom."
Seeing the expression on her daughter's face, Teresa looked at me next, her eyes telling me she was grateful that I'd been caring enough to leave Karen as happy and content as she obviously was — along with something else that I couldn't quite figure out. Telling Karen and me "You two sit down, and I'll fix you something.", she got up and made her way toward the kitchen. When I looked at Donna and Wendy, I could see that both of them knew that something special had happened, but didn't have a clue as to what it could be. But both were too polite to inquire about it directly, and simply did their best to set it aside and make conversation with me and Karen. A couple minutes later, Teresa was back with more of the waffles that they'd all been having. From there, breakfast went pretty much as it usually did.
Teresa and I were in the living room after breakfast when she told me "Ted, I know you and Karen have been… intimate. Even more than before, I mean. She talked to me about it a little bit before, so I know it wasn't your idea; and I just want to say that I'm glad you were able to make her first time as good and easy as you obviously did. It's something that had to happen sooner or later, and I knew that you'd be as patient and gentle with her as she needed. I wish to hell I'd felt like that after my first time!"
I didn't say anything, and Teresa went on to say "Anyway, thank you for making her as happy as you did. I don't think for a moment that'll be the only time she wants to be with you like that, so I want to make sure you know that I don't mind. I told you I trusted you about things like that, and I just have to look at Karen this morning to see that I was right. If, or when, Donna or Wendy come to you… well, I know you'll be just as careful with them — so don't worry about me."
"I'm not looking for any of this to happen", I told her — "I know that, Ted." — "but if things get to that point, then I promise to do my best for them."
"I know that, too.", she answered with a smile.
Any further conversation was interrupted by the appearance of the girls, who wanted to watch Saturday morning cartoons. After directing me to lean back against the arm of the couch, Karen parked herself in my lap; when I'd put my arms around her, she leaned back against me and rested her arms on mine before releasing a small sigh of happiness. Neither Donna nor Wendy gave any indication that they were put out by what Karen had done; both seemed to figure that it was simply a continuation of whatever specialness that was going on with their sister and me.
After that morning, Karen didn't act as though she had any special rights or privileges that her sisters didn't; and I continued to treat her the same as I did them — except when we were alone.
Donna and Wendy both continued to come down to visit for an evening, or spend the night with me, and they were always welcome. When Karen came down, I was just as glad to gently molest her as I was her sisters; if she spent the night with me, it was her choice as to whether or not we made love. I wasn't reluctant to try and initiate things, but if she indicated she didn't want to for any reason, then I certainly didn't press the matter. Other times, it would be all I could do not to have her all but dragging me to bed for a bout of intense fornication. Either way, I loved her and her sisters with all my heart.
It was several weeks later, and Teresa had been asked to go in on a Saturday to help with a big project — something important enough that she told me not to expect her until after supper. That left me pulling duty as Authority Figure for the day, which was fine.
Wendy had gone off to visit one of her friends that had gotten a new stereo for her birthday, which left me and the two older girls in the house. They spent a couple of hours with me in the living room, then went back to their bedrooms when I said I wanted to watch sports. When the game I'd been watching ended, I went back to see how they were doing; I checked Karen's room first, and found it empty. After I'd knocked, then opened Donna's door, I was greeted by the sight of the two of them naked on Donna's bed — and engaged in an intense session of "69". I quickly closed the door as quietly as I could, then went back into the living room, where the memory of the sight of the two of them pleasuring each other soon had me sporting an erection. Try as I might, I couldn't get the image of them out of my mind, and was starting to give some thought to perhaps relieving my desires myself when both of them came walking into the living room, stark naked.
When I raised an eyebrow at them, it was Donna that asked "Uncle Ted… did… did you look in my room a little while ago?"
"Yes. I just wanted to see how you and Karen were doing, was all. I saw you were busy" — both blushed faintly at that — "so I closed the door again. Why? Did I disturb you?"
After they'd taken seats, Karen asked "You… you don't think we were doing anything wrong?"
"No, not at all. Didn't I just ask if I disturbed you? Don't you think if I thought you were doing anything wrong, I would have said something when I saw you?"
They looked at each other for a few moments before Karen told me "Well, Mom didn't really talk to us about stuff like that. I mean, she told us about guys and everything, but not about being with another girl; and both of us have heard other people talk about it, and most of the time, it sounds like they think it's bad, somehow."
"I don't doubt that it sounded like that to you, but I don't agree. I think that most of the time, when you hear someone talking that way, it's because they're afraid inside, or because they somehow think that they have the right to try and tell other people how to live. There are probably a lot more like me that think that whatever two people want to do together is their business, and nobody elses. I didn't see either one of you holding a gun or anything, so I don't think either one of you was forcing the other one. If both of you were there because you wanted to be, then there's nothing for me to say about it."
"Then it didn't gross you out, or bother you, or anything?", Donna asked.
I had to smile as I answered "No, none of that. In fact, I thought it looked pretty sexy."
Both of them were plainly baffled when Donna asked "You thought it looked sexy? Why?"
"I think that watching two women making love is something that a lot of guys think is sexy. I don't think that I can really explain it, except maybe to say that when it's two women together, they're doing what we'd like to do — only there's twice as much of it. That, and we like to think that a woman is really excited when we're with her, and when it's two women together, then we know that they are excited, because they wouldn't be doing what they are if they weren't."
Karen was the one to ask the obvious question "Did you think WE were sexy like that? You liked watching us?"
"Yes, I did. I've told both of you that I think you're sexy by yourselves; why wouldn't I think that you were even sexier when you're together like that?"
Donna wanted to know "Did… did seeing us make you excited?"
Once again, my commitment to being truthful and honest with them was biting me on the ass; there wasn't anything for me to do but answer "Yes, it did."
To my surprise, I saw two pairs of nipples begin to erect before the two of them exchanged another look. When both were facing me again, Karen asked "Would you like to watch us?
And… and maybe even do things with us? Both of us, at the same time, I mean?"
Golly-gee willikers, now there was a question I never thought I'd hear — did I want to watch two nubile young women getting each other off, with the option of joining in?
I (barely) managed to contain my enthusiasm as I answered "If you really don't mind, I'd like that very much. Watching you, and doing things with both of you, too."
The two of them were clearly pleased to hear my answer before Donna stood up, followed by Karen doing the same. It took me a moment longer, and both girls saw by the tenting of my pants that I'd been telling the truth about liking what I'd seen. Both gave me a happy smile before each took one of my hands and got us moving down the hall. When we got into Donna's room, I could still smell the delicious aroma of aroused female, and felt myself get a little harder in response.
